Utilising new technology to optimise nitrogen use in broadare cropping protect the soil resource and minimise potential offsite impacts. This project seeks to quantify the level of N variability within broadacre cropping in Southern NSW using intensive grid deep N sampling, and subsequently examine the suitability of other existing and emerging technologies (yield, protein, ECa and NDVI) to inform scientifically robust Variable Rate N applications.
